Therefore, it has been classified as a Variant of Uncertain Significance. Nucleotide substitutions within the consensus splice site are a relatively common cause of aberrant splicing (PMID: 17576681, 9536098). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with RAD51C-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces arginine with lysine at codon 322 of the RAD51C protein (p.Arg322Lys). The arginine residue is highly conserved and there is a small physicochemical difference between arginine and lysine. This variant also falls at the last nucleotide of exon 7 of the RAD51C coding sequence, which is part of the consensus splice site for this exon.
